I have a 2018 Sierra 6.2 with Kooks headers, Kooks cats and K&N CAI. I've been thinking about installing a Whipple or a Procharger but I'm considering nitrous too. I'm looking at a Nitrous Express 20936 kit. I just want the extra occasionally and I'm concerned that the supercharger noise will be annoying. Anyone using nitrous on their similar truck?
